1) Introduction: Urea Structure Explained

Urea Structure Explained
Urea structure explained covers the chemical composition, properties, and biological significance of urea. Chemically represented as (NH₂)₂CO, urea is an organic diamide of carbonic acid. First synthesized in 1828 by Friedrich Wöhler, it marked a milestone in organic chemistry as the first compound produced from inorganic materials.

Urea’s molecular structure consists of two amino (NH₂) groups bonded to a central carbonyl (CO) group. This planar configuration allows urea to interact with water, proteins, and other molecules, making it versatile for industrial, agricultural, and medical applications. Its ability to dissolve in water and act as both an acid and base underpins its diverse uses.

Understanding urea structure and its functions sets the stage for examining its effects on protein folding, metabolic roles, and industrial applications.
